Package hephysics.jet Description

Java implementation of the longitudinally invariant kT, Cambridge/Aachen and anti-KT clustering algorithms using the recombination method.

JetN2 - a jet algorithm that uses N**2 geometrical approach, similar to C++ FastJet.
SCJet - a traditional N*3 algorithm
KTjet - uses pseudorapidity and float values. A fast light-weight implementation.

Note: Use JetN2 where possible. This algorithm has a speed similar to C++ FastJet.
